accessing ccsprite from another class

Question

in A.h i write like this

@interface A
{
  CCSprite *loadingSprite;
}

- (void)getTag;

@property (nonatomic, retain) CCSprite *loadingSprite;

@end

then in implementation A.m

@synthesize loadingSprite

- (id)init
{
 loadingSprite = [CCSprite spriteWithSpriteFrameName:@"loading-icon1.png"];
 [loadingSprite setTag:111];
 [self addChild:loadingSprite];
}

- (void)getTag
{
 NSLog(@"%@ tag %d",[loadingSprite getChildByTag:111] , [loadingSprite getChildByTag:111].tag)
}

on another class, B.m i write to access method getTag

A *a = [[A alloc] init];
[a getTag];

but unfortunately, the NSLog in getTag shows :

(null) tag 0

how the proper way to access the ccsprite from another class? thanks
